We need more information. Did you claim a qualified dependent child? In the first tax year that your spouse passes away, you can file a joint return. For the next two years, if you claim a dependent child, you can file as a qualified surviving spouse and you get the same standard deduction as a the amount for a joint return. If you filed "single" but have a qualified dependent child to claim, wait for your return to be fully processed and then you can amend to change your filing status to QSS. If you do not have a dependent child, then "single" was the correct filing status.
Wait until your original return has been fully processed before you amend, and make sure you have saved a pdf of the original return before you amend. (If you do not save it as a pdf, the amended return will overwrite the original, and the original will be lost forever)
